use differencing disks. that point to your MASTER copy as the source disk and each has theirn own differencing disk. &nbsp;(stores the differences from the master) .. you should sysprep the master copy first to eliminate any potential conflicts.

&nbsp; Are you referring to this? I don't see &quot;differencing disks&quot; option.

Ok. I will just create one VM at a time.

once you sysprep the master you should not use it again just use the differencing disks

Hi,<br />
&nbsp;<br />
&nbsp;I have created a new VM (XP operating system) in Windows Server 2012 Hyper-V.<br />
&nbsp;I installed all the basic software, printers .. etc and need to set up three more identical VMs with XP.<br />
&nbsp;Instead of spending a few hours to set up each VM from the scratch, is there a way to duplicate existing VM?<br />

Hi,
 
 I have created a new VM (XP operating system) in Windows Server 2012 Hyper-V.
 I installed all the basic software, printers .. etc and need to set up three more identical VMs with XP.
 Instead of spending a few hours to set up each VM from the scratch, is there a way to duplicate existing VM?
 Afterwards I like to change computer name, and join each VM to the domain controller and activate the XP OS?

Duplication of Virtual Machine on Hyper-V 2012

Windows Server 2012 is the server version of Windows 8 and the successor to Windows Server 2008 R2. Windows Server 2012 is the first version of Windows Server to have no support for Itanium-based computers since Windows NT 4.0. Windows Server 2012, now in its second release (Windows Server 2012 Release 2) includes Foundation, Essentials, Standard and Datacenter, and does not support IA-32 or IA-64 processors.

Windows Server 2012

Hyper-V is a native hypervisor; it can create virtual machines on x86-64 systems and supersedes Windows Virtual PC as the hardware virtualization component of the client editions of Windows NT. A server computer running Hyper-V can be configured to expose individual virtual machines to one or more networks. Hyper-V Server supports remote access via Remote Desktop Connection. Administration and configuration of the host OS and the guest virtual machines is generally done over the network.

Hyper-V

Microsoft Windows XP is the sixth release of the NT series of operating systems, and was the first to be marketed in a variety of editions: XP Home and XP Professional, designed for business and power users. The advanced features in XP Professional are generally disabled in Home Edition, but are there and can be activated. There were two 64-bit editions, an embedded edition and a tablet edition.
